methanol Chem.|ˈmɛθənɒl|
[f. methane + -ol.]
Methyl alcohol, CH3OH, a colourless, volatile, poisonous liquid with a pungent odour which is produced mainly by the high-pressure reduction of carbon monoxide or dioxide with hydrogen and is used as an intermediate in the synthesis of formaldehyde, as a solvent, and as a denaturant for ethyl alcohol.
The adoption of methanol as the systematic name of methyl alcohol was a consequence of Resolution 15 (on alcohols and phenols) of the report of 1892 of the International Conference on Chemical Nomenclature (see Nature (1892) 19 May 58–9).
